Exposure Unverified

The expected crashes behind this grade assume the filed fleet of 1239 power units is real, but the roadside record corroborates little of it — 163 units seen in 24 months, 0.07 inspections per filed unit-year. The grade's relativity to class is unchanged; its confidence tier is cut to reflect the unverified exposure, and until the fleet is confirmed an Excellent grade shows as Strong and a Strong as Satisfactory. Verify the fleet size before relying on the crash expectation.

Mileage Unreliable

MCS-150 annual mileage appears too low for fleet size given observed activity. The per-100k-mile rate benchmarks on this page are excluded; the FRED grade does not use mileage (crash exposure is power-unit-years, violation exposure is inspection counts).

Expected crash rate is probably lower than similar fleets (about an 80% chance), but the record is too thin to say by how much.

Similar fleets: for-hire fleets of 500+ trucks with the same kind of operation, years in business and amount of road activity. Compared using its own crash record and roadside inspections.

What's driving the grade
Crash history
betterworse
About typical. 19 crashes on the FMCSA record in 24 months (about 9.5 a year), including 8 with injuries; similar fleets have about 13 a year. The grade counts 44 crashes in its 36-month scoring window, recent ones weighted most.
Roadside inspections
betterworse
Better than peers. Unsafe-driving and hours-of-service violations 0.54× the rate expected for its inspections. Together they move its crash estimate -10%: roadside results weigh far less than crash history.

Worth a closer look

From the FMCSA record. The grade already counts the safety items; insurance filings and links to other motor carriers are not in it.

  • Injury crashes
    8 crashes with 9 people hurt in 24 months.
    Ask: claim status and driver history for these crashes.
  • Drivers put out of service
    9 out-of-service violations against drivers: 4 no valid CDL, 3 cargo securement, 2 hours of service (Sep 2024 – Jun 2026).
    Ask: driver supervision and dispatch practices.
  • Lights and brakes
    Lights are 45 of 143 violations (31%). Light or brake defects led to 12 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Filed fleet not seen on the road
    Only 163 of the 1239 filed power units were seen at a roadside inspection in 24 months (186 inspections in all). The crash expectation behind the grade assumes all 1239 are running.
    Ask: how many trucks are actually operating, with the vehicle schedule.
Strengths
  • Vehicle out-of-service rate 13.8% vs 22.3% national; driver 4.5% vs 6.7%.
  • No FMCSA BASIC alerts.
Data flags
  • Dangerous driving: 5
  • High speeding: 6
  • Unreliable reported mileage
    The motor carrier's self-reported annual mileage (MCS-150) looks implausible, so exposure- and mileage-based figures may be distorted.
  • Estimated mileage
    No usable mileage was reported, so exposure was estimated from similar motor carriers. Mileage-based metrics here are approximate.
